Hypherator is a lightweight, MIT-licensed hyphenation library for Java, based on Hunspell-style hyphenation patterns. It provides a simple iterator-based API to hyphenate words — making it easy to integrate into tokenizer-style workflows (like ICU4J).

• 🔤 Hunspell-style hyphenation rules (used by LibreOffice and OpenOffice)
• ⚙️ Lightweight & pure Java – no native code or JNI required
• 🔁 Iterator-based API – works great in streaming/text processing pipelines
• 🌍 Multi-language – bundled with broad collection of hyphenation dictionaries
• 🆓 MIT license – free for commercial and open-source use

implementation("io.sevcik:hypherator:1.0")

        String word = "typography";
        HyphenIterator iterator = Hypherator.getInstance("en_US");
        iterator.setWord(word);
        var potentialBreak = iterator.first();
        int count = 0;
        while (potentialBreak != DONE) {
            var parts = iterator.applyBreak(pb);
            System.out.println(parts.getFirst() + " - " + parts.getSecond());
            potentialBreak = iterator.next();
        }

This will print possible hyphenation points like:

ty - pography
typog - raphy

Compatible LibreOffice hyphenation dictionaries are bundled directly, so Hypherator works out of the box for many languages — no extra setup required.
